Kubernetes -env and -envFrom environment variables setting

Can Kubernetes deployment manifest file have both -env and -envFrom keys?

I have set a secrets.yaml file to set the environment variables and also have environment variables that are hard coded.

Can I have both of them set using both -env and -envFrom in the YAML files?

  • Can kubernetes deployment manifest file have both -env and -envFrom keys?

    Yes.

    ...
envFrom:
- secretRef:
    name: <name of your secret>
env:
- name: <variable name>
  value: <hardcoded value>

- name: <variable name>
  valueFrom:
    secretKeyRef:
      name: <name of your secret>
      key: <If I only want this and not all the keys in the secret>
